Thread is a little old but the question is still relevant as both apps continue to improve over time.
I've used MMR for tracking rides then upload my data to Strava. I like Strava's service better over all but continue to use MMR for tracking rides because it tracks in small increments. 10.01, 10.02, 10.1 ect. Strava only in full tenth mile increments.
I was wondering if Strava keeps track of the hundredths and adds to your weekly and monthly totals, or does it just drop those?
